Pramati Server 3.5 Administration Guide

abstraction of a single processing server for operations such as configuration, tuning, deployment

and monitoring.

A Pramati Server Cluster node can be of three types: EJB, Web and BOTH. Pramati Server can be

configured as a Standalone node or a Cluster node. Application components may be deployed on the

Server in one of the following ways:

• Locally (without Load Balancer): The application is deployed individually on one or more

independent Standalone nodes on the network. An external or Pramati HTTP Server directs

requests to each Server

• Clustered (with Load Balancer): Multiple Cluster nodes act as a single Server and balance

application request loads.

Pramati Server Cluster EJB node

In an EJB node, only the EJB container gets started and the Web container does not. This is

advantageous when the application consists of only EJBs.

Pramati Server Cluster Web node

A Web node is used when the application uses static HTML, JSP and Servlets. A Web node

configured as a Standalone server can act as a Load Balancer.

Pramati Server Cluster BOTH node

While configuring a Cluster node, the Server Administration Service provides the option to select

EJB or Web or BOTH type of node. The BOTH option is selected when the application uses Java,

EJBs, JSP and Servlet components. This options can be enabled while configuring a new node.

Pramati Embedded Message Server

Embedded Message Server runs in the same VM as Pramati Server. It is part of the Default Pramati

Server configuration and can be optionally started every time the Server starts. This can not be a part

of the EJB/WEB/BOTH node.

Pramati Server Standalone Message Server node

Pramati Message Server can be set up as an independent, full-function Pramati Message Server to

process enterprise Java messaging applications. The Pramati Message Server High Availability (HA)

Solution enables failover for JMS applications.

Pramati Server Load Balancer

Pramati Server Load Balancer is an HTTP-aware Web Traffic Management Interceptor that acts as a

request dispatcher and performs intelligent forwarding of requests based on pattern, load, session

etc. It integrates with other commercial application servers, thus making it a cost effective solution

for many enterprises willing to adapt a sophisticated traffic management setup.
